Patent CA-2266076-C (CA)
Inventor: GUSTIN JAY W
IPC: G06F13/42

Abstract: A control circuit for the interface circuit of a module of a distributed process control system permits its kernel submodule and peripheral submodule to communicate through the interface circuit notwithstanding that the structure and protocol of module BUS of the kernel submodules is incompatible with the structure and protocol of the PCI  BUS of the peripheral submodule. The control circuit includes a module BUS state machine (MBSM), a PCI target state machine (PTSM), an arbiter state machine (ARSM), and an address decode logic (ADL) circuit. In response to control signals from the kernel and peripheral submodules applied to the control circuit over their respective buses, and control signals produced by the MBSM, the PTSM, the ARSM, and the ADL circuit. Which one of the two submodules is granted access to the registers of the interface circuit is determined by the control circuit which also grants the peripheral submodule access through the interface circuit to the memory of the kernel submodule. If both submodules request access to the interface circuit at the same time the peripheral submodule has priority. The control circuit prevents either submodule from successive accesses to the interface circuit if the other submodule has a request for access pending.

Abstract: A non-oriented electromagnetic steel sheet comprises about 0.01 wt% or less of C, greater than about 1.0 wt% and at most about 3.5 wt% of Si, at least about 0.6 wt% and at most about 3.0 wt% of Al, at least about 0.1 wt% and at most about 2.0 wt% of Mn, at least about 2 ppm and at most about 80 ppm of one or more rare earth metals (REM), a maximum content of Ti and Zr being about 15 ppm and 80 ppm, respectively, wherein oxygen on a metal surface layer of the steel sheet is 1.0 g/m2 or less after finish annealing. A method of manufacturing the non- oriented electromagnetic steel sheet is also disclosed. Since the non-oriented electromagnetic steel sheet has desirable mechanical properties resulting from the increased amounts of Si and Al, a high magnetic flux density can be maintained without sacrificing a punching property as well as very low iron loss can be obtained even after stress relief annealing.

Abstract: A sound pressure waveguide consisting of an input acoustic channel, a compression zone and exit channel with an optional termination baffle. The shape and length of the waveguides are varied to adjust sound pressure gain and to achieve varied sound pickup directivity. The shape and length of the termination baffle, when employed, is also adjustable to achieve varied directivity. The waveguide is shaped from at least two opposing members or sides and at least one sloped member or side. The mounting position of one or more commercially available microphone transducers) puts the transducer's diaphragm substantially parallel to the sound path through the waveguide pressure channel. The exit channel is included to let sound pressure pass by the microphone to the pressure channel and through the waveguide to an optional termination baffle, thus preventing significant pressure distortion, sound pressure propagation distortion and undesirable reflections.

Abstract: L'invention concerne un anneau (100) anti-contournement comprenant un corps (104) sensiblement cylindrique doté d'une surface extérieure (108) présentant plusieurs passages (102). Chaque passage (102) s'étend d'une des parois latérales (106, 107), à travers le corps, à l'autre paroi latérale (106, 107) de l'anneau (100). Les passages (102) permettent d'établir une communication fluide entre le milieu entourant un produit accessoire tel qu'un isolant de traversée (10) et l'intérieur d'un connecteur monté dessus, lorsque le connecteur (12) est enlevé de l'isolant de traversée (10). La communication fluide permet d'éviter la formation d'un vide entre le connecteur (12) et l'isolant de traversée (10), vide pouvant entraîner un contournement entre une sonde électrique dans le connecteur (12) et un blindage de masse (14) de l'isolant de traversée (10). L'anneau (100) anti-contournement est également configuré de manière à indiquer à l'opérateur installant le connecteur (12) le moment où le connecteur (12) est complètement installé sur l'isolant de traversée (10). On peut obtenir ces indications en dotant l'anneau d'une largeur égale à la longueur du rebord du connecteur lorsque le connecteur (12) est complètement installé. Ainsi, l'opérateur installant le connecteur (12) continue de pousser sur le connecteur (12) jusqu'à ce que l'extrémité du rebord s'aligne avec l'extrémité de l'anneau (100).

Abstract: A refrigerant dispensing tool includes a three section body with a top manifold section having an evacuation port, a refrigerant supply port and an oil supply port. The intermediate body section has three elongated and converging valve chambers which connect with the corresponding ports and receive corresponding elongated fluid pressure balancing valve members. The valve members are independently operated and precisely controlled by corresponding air actuated pistons which receive pressurized air from corresponding air ports within the manifold section. An air actuated and spring biased annular piston is supported between the intermediate and base sections of the body and operates a set of circumferentially spaced balls which releasably clamp the tool to a stem valve fitting for a refrigerant system. An air actuated pin extends on the center axis of the body for opening and closing the valve stem within the fitting, and a resilient sealing ring forms a fluid-tight seal between the base section and the fitting.

Abstract: A recovery plant for recovery of a gaseous component, such as carbon dioxide, from a process gas, such as the exhaust from a combustion turbine, has an absorber (110) employing a lean solvent (126) in an upper section of the absorber and a semi-lean solvent (172) in a lower section of the absorber. A regenerator (120) extracts the gaseous component from the rich solvent (117) thereby producing a regenerated lean solvent (126) and a semi-lean solvent (127). A solvent flow control element (170) combines at least a part of the semi-rich solvent (118) from the upper section of the absorber with the semi-lean solvent (127) from the regenerator to form a mixed solvent (171), and a cooler (112) cools the mixed solvent that is subsequently fed into the lower section of the absorber (110). By cooling the mixed solvent prior to entry into the absorber, the thermal energy required to remove the carbon dioxide from the exhaust gas can be reduced.
